LINED SHEET-METAL BARREL.

Application filed June 1a, 1923. Serial N'o. 645,084

To all whom it may concern: '2

Be it known that I, Anonrrr F. LINDGREN, a citizen of the United States; residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Lined Sheet-Metal Barrels,

of which the following is a specification.

This invention relates to a lined sheet metal barrel. As is well known sheet metal barrels as heretofore constructed have been unlinedand the use of the same has therefore been limited to such articles which.

a container.

would not be injuriously affected by direct contact with the metal. The absence of a lining therefor excluded the use of' sheet metal barrelsfor use in packing and shipping fruit which by contact with the metal suitable material best suited for the particular material or articles which are to be packed, stored or shipped in the sheet metal With this end in vie w this invention consists generallypf providing asheet metal barrel on/its inner side with" a protective 85c lining, andspecifically with a linin which is co-extensive with the inner surfaces of the sheetmetal shell of the'barrel or container and which' lining is held in place by 7 extending the same into the interlocked parts of the body and heads of the sheet metalshell of the barrel so that this lining is clamped between such arts and reliably held in place while in use. i

In thezaccompanying drawings: Figure 1 is a blank of the body portions -..of the shell and lining which are superimposed and have been partly prepared for conversion into the body of the completed barrel,'cask or container. Figure 2 is an end view of this blank with the longitudinal edgesbent or folded ba kwardly to form locking hooks thereon. igure 3 is an edge view of one of the longitudinal edges of the blank showing the opposite ends of the same provided with a double fold for use in fastening the heads to opposite ends of the body edges locked together.

still in a flat condition,

Figure 6 is a fragmentary longitudinal see.-

Similar characters of reference indicate like parts in-the several figures.

As a whole the barrel containing my in vention comprises a'body of tubular form,-

and two heads arranged the body, one of these imperforate,

at opposite ends of heads being solid or while the other head is pro vided with an inlet or filling opening which closed, by a detachable cover.

is normally The strength of the barrel is derived from an outer shell which is constructed of sheet metal and the protection on its inner side is attained by a lining applied to the inner side of the shell.

The body 10 of the shell is constructed of a sheet of metal .of the desired character, such for instance as sheet iron, which is provided at its opposite longitudinal edges with notches 11, while this sheetor plate is 1. After this sheet metal blank has been thus notched each of its longitudinal edges is bent or doubled upon itself between the corresponding notches 11 so as to form a hook-shape flange 12 on the outer side of this blank; asfshown in Figure 2. The transverse edges of this sheet metal blank are then bent so that a double .fold of the metal is produced at each endof the same on the inner side thereof, each of these double folds consisting of a longitudinal intermediate web 13 which is arranged on the inner side of the body portion of the sheet metal shell and is connected at its outer edge with the latter, and an inner hook-shape flange 14 which is spaced apart from the inner side of the correspondmg'web so as to form a channel therebetween and is connected at its inner edge with the corresponding edge of the web. This web is comparatively wide as shown in Figure 'of the barrel. Figure t is a perspective the locking bar are connected with each I while the flange 14: is narrower than the web, for instance the web being twice the. width of the flange, as shown in the draw? ings, whereby the outer edge portion of the web and the corresponding edge portion of the-body of the shell roject beyondthe Outer edge of the hook ange' 14. I

While the body blank of the shell of the barrel is being thus prepared and provided at its edges with single and double folds as, above described, a sheet 15 of paper or other suitable protecting material is mounted or arranged on the inner side of the sheet metal body blank of thebarrel and subjected to the same notching and folding operations at its several edges so that this body SQCUOIFOf the lining is co-extensive with the companion section of the sheet metal shell and covers not only the inner side of the latter within the boundaries of its edges, but also follows the corresponding inner sides of the 1 several longitudinal single fold hook flanges ranged on an outer ply of and also the transverse double folds at opposite transverse ends of the body portion of the shell. Thus, in effect, the body of the barrel consists of two plies of sheet material, a

sheet metal and an inner ply of paper or other protective material which plies are co-extensive throughout their sur-' faces and therefore form longitudinal hook shape portions 16 on the inner side of the longitudinal hooks 12 of the shell, intermew diate webs 17 each of which is connected a5 7 an arranged on the inner side of the same and hook-shaped flanges 18 each of which 1s arthe inner side of one of the webs and connected at its inner edge therewith,

After the sheet metal flanges at the said web being comparatively wide and the hook flan e narrow, corresponding to the relation 0 the companion parts of the metal *shell.

and-the upper lining constituting the bod blank of the barrel have been thus provi ed with single folds at A the opposite longitudinal edges of the same, and with double folds at the opposite trans-ii verse or end edges of the same this two-ply blank is rolled or bent into. the form of a tube or cylinder so that the double folds of' the same are arranged on the inner side of the cylindrical \body and the single hook opposing longitudinal edges the outer side of the body longitudinal hook other but are and the longithereof are on At this time thesev two flanges are opposed to each turned away from each other,

tudinal hook portions of the lining are in contact with each other so' that only the protective lining is exposed circumferentially on the inner side of the two-ply body of the barrel. At the same time the double folds at the opposite ends of the two-ply barrel body ',are bent into circular form The two longitudinal hook-shape flanges 12 :vening annular space.

of the barrel body are drawntogether so as to hold the protective lining on these parts of the shell firmly in engagement with each other by means of a locking bar which preferably consists of a sheet metal web 19 adapted to engage; withthe outer sides of the lined hooks 12 of the shell and provided at its opposite longitudinal edges with hook with the channels formed between form of disks 21 and 22, each of these disks i being provided at its peripheraledge with an outwardly projecting circumferential web 23 which is connected at its inner edge with the respective head disk, and a hook-shaped flange 24 surrounding the web 23 but separated therefrom by an intervening circumferential channel and connected at its outeredge with the corresponding edge of the web 23, as best shown in Figure 6. On its inner side and-co-extensive with the disk, web and flange of each head is arranged the head section of the protective lining of paper or the like for this part of the barrel shell, which protective section comprises a central disk 25 engaging with the inner side of the disk of the corresponding head, (a web 26 projecting outwardly from the margin of the disk 25 and connected at its inner edge therewith, and a flange 27 surrounding the web 26 and connected at its outer edge therewith, but separated therefrom by an inter- The' lining section for each .head is applied thereto while these parts are still in a flat conditionand in effect form two plies of Head material and thereafter these two plies are bent simultaneous! y into the shape described so ,that they are co-extensive throughout their areas. After the heads have beein thus formed of two plies of material each, an outer'ply or section of sheet metal, and an inner ply of protective material, such as paper the heads and body of the barrel'are assembled by engaging the peripheral flan e of each head with one of the circumferential channels formed at one end of, :the barrel body between the web and hook flange at the corresponding end of the body, and simultaneously engaging the hook flange at this end of the body with the annular channel formed between the hook flange and web of the respective head of the barrel. When the parts are thus assembled the hook portion 18 of the lining of the body engages with the web portion 26 of the lining of the respective head, as shown in Figures 5 and 6 so that these parts of the metal surfaces of the locking joint between surfaces are exposed or accessible to the materlal which is contained within the re ceptacle. f I

A-fter the heads and body of the barrel have been thus assembled these heads are securely held in place on the body by bending inwardly the outer portions of the webs l3 and the adjacent portions of-thebody 10 of the shell and the corresponding parts of the lining therein, so that these 'inwardly turned parts overhang and engage with the outer ends of thehook flanges and webs of the barrel heads, as shown in Figures 5 and 6 and securely unite these parts so that they will not come apart when subjected to use.

The filling opening is formed in the central part of the upper head and in order to provide a good seat in the same for the cover which closes the barrel and also to permit of lining this part oft he barrel so as to cover up the internal-metal surfaces of the same an outwardly curled head 28 is formed on the metal disk of this head and the adjacent part of the the protective lining of this head is also turned outwardly and around this bead in the form of a curled flange or bead, as shown at 29, in Figure 5. I

-Although the cover for this filling opening may be variously constructed the same, as shown in Figure 5, comprises an outer section, of sheet metal andi an inner section of protective lining, the two plies of which are co-extensive as to area so that no part of the inner surface of the metal section of this cover. is exposed on the interior of the receptacle or barrel. The outer section of the cover is stamped out of sheet metal so that it is downwardly dished and forms a side wall 30, a flat inner crown 31 connected with the inner edge of the side wall and a laterally projecting annular rim 32 arranged attheouter edge of the side wall 30. The inner section of this cover which forms the protective lining therefor is constructed of paper or similar material so as to form an inner flat crown 33 arranged on the inner side of the crown 31 of the metal section'of the cover, a side wall 34extending along the corresponding inner side of the wall of the metal cover section, and a laterally projecting rim or flange 35 arranged on the inner side of the flange or rimv 32 of the metal cover section. When in use the inwardly dished part ofthe two-ply cover is inserted in thefilling opening of the perforated head of the barrel so' that the wall portion of the protective lining on the cover engages with the outwardly curled bead portion 29 of the protective lining on the perforated head of the barrel, as shown in Figure 5, thereby forming noton'ly a tight joint between the cover! and the perforated head but also preventing contact of the contents of the baron in a manner common to-thisxtype ofrel with any of the metal surfaces of the cover or the adjacent head. After the barrel has been filled with the desired material and the cover has been introduced into the filling opening of the same, this cover may be held in place'by any suitable or approved means, for instance, this may be accomplished by swellin the lowerpart of the side wall of the cover, as shown at 36, to-

gether with the adjacent part of the lining -means, but instead requires the' head to be destroyed before it can be removed as is customary in this class ofcovers. a

If desired the body of the barrel may be strengthened .by forming circumferential re-inforeing heads or corrugations 37 there- .A barrel, keg or container constructed in accordance with this invention cannot only be manufactured at low cost, but it also holds the protective lining securely against displacement on the inner side-,of the metal shell and insures a complete coverage of the metal surfaces by means of the, protective liningso that any materials packed therein bar-i will be protected against contamination or,

injury or chemical reaction.
